bq2403x (bqTiny-III™) 1.5-A Single-Chip Li-Ion
and Li-Pol Charge Management IC EVM
This user’s guide describes the bq2403x (bqTiny-III™) Evaluation Module. The EVM
provides a convenient method for evaluating the performance of a charge management
and system power solution for portable applications using the bq2403x product family.
A completly designed and tested module is presented. The charger is designed to
deliver up to 1.5 A of continuous current to the system or charger for one-cell Li-ion or
Li-polymer applications (see the data sheet for correct device, x) using a dc power
supply. The charger is programmed from the factory to deliver 1 A of charging current.
